“In climate research and modelling, we should recognize that we are dealing with a coupled non-linear chaotic system, and therefore that long-term prediction of future climate states is not possible.”

4. The Computer Climate Model
Clockwork Fallacy
Model forecasts are
“based on well-known equations of conservation of momentum, mass and energy and the equation of state.”
“Global climate models are based on the laws of physics; they make no assumption of climate constancy or inconstancy.”
